Me (20M) (white) and my girl friend (18F) (black) had a really bad fight last night
My (20M-white) girlfriend (18F-black) got sent a text on snap by a burner account. In the text they said that I'm an awful person, that I'm racist about her, that I openly talk about our sex lives, and just stuff of that nature. Along with that was an old picture of me from 6 years ago with the a racist song over it. I don't know how I can prove to her that it's not me. I was a freshman in high school and made a really stupid choice but l've since grown as a person. We've been together for just over 3 months and I have never talked disrespectfully about her behind her back nor talked about our sex lives.
We had a long call last night about this and she said that she would let me try and prove it to her. I just don't know how to move forward. Do I just have to give her space? Do I try to act the same way I did before this person messaged her? I just don't know how to prove that what they said isn't true.
